Currently, when you go to the browse worlds under the community tab, you often see many worlds that you already follow. This, in my opinion, is against the idea this feature serves. It is supposed to help find new worlds to read and follow. Because of that I propose that worlds that a user already follows did no appear in the browse worlds.
I don't know if that is possible, but it would be a useful thing to have
While this can be helpful, there have been plenty of times that I vaguely remember a world that someone might have that I'm following, so I got to look it up. If this is put in place, I won't (nor would others who do the same thing) be able to find said world that I follow, especially if I have 100s of worlds that I follow and would have to sift through just to find that one world, which could easily pop up via the browse worlds feature.
Maybe a filter to filter out worlds you follow would be easier and more helpful.
I do not believe this provides any noticeable benefit, while potentially causing confusion by people who can not find a world they are already following.
